Why You Should Change the Door Locks on Your New Build Home After Moving In

Moving into a new build home is an exciting milestone!

The fresh paint, untouched floors, and modern features all contribute to a sense of security and comfort.

However, there’s one often-overlooked aspect of home security that new homeowners should consider immediately after move-in: changing the locks.

While a brand-new home might seem like a blank slate, there are several reasons why replacing or upgrading your door locks should be a top priority.

Even after moving in, you might still have contractors or service providers coming in and out of your home—whether it's for flooring upgrades, fresh paint, window treatments, or deep cleaning services. If you're handing out spare keys or leaving your home unlocked for workers, it's easy to lose track of who has access.

By updating your locks after all work is complete, you ensure that only you and your trusted family members have the keys to your new home.

From added security to high-tech features, let’s explore why this simple step is an important investment in your home’s safety.

1. Who Has Copies of Your Keys?

One of the biggest concerns with new build homes is that multiple people likely had access to your house before you moved in.

Potential Keyholders Could Include:

• Construction workers – Builders, subcontractors, and contractors may have had access to a master key system to enter the home for installations and repairs.
  

• Realtors or site managers – If your home was part of a model home development or had showings before purchase, sales teams might have used a universal key.
  

• Inspectors and vendors – Home inspectors, cleaning crews, and even warranty repair teams may have been granted access during the final stages of construction.
  

While most professionals are trustworthy, you have no way of knowing if extra copies of your keys exist or where they might be. Changing the locks ensures that only you and your trusted family members have access to your home.

2. Upgrading to Higher Security Locks

Most builders install basic locks to keep costs down. These locks are often standard-grade hardware, which may not provide the best level of security.

Upgrading your locks gives you the opportunity to install higher-quality deadbolts, smart locks, or even biometric entry systems.

Types of Lock Upgrades to Consider:

• Heavy-Duty Deadbolts – Look for ANSI Grade 1 deadbolts, which offer the highest level of security.
  

• Keyless Entry Locks – Avoid the risk of lost or stolen keys by opting for a keypad entry system.
  

• Smart Locks – Control your locks remotely from your smartphone, give access codes to guests, and track entry activity.
  

• Biometric Locks – Fingerprint-based locks add an extra layer of security and convenience.
  

Newer locks also tend to be more resistant to lock picking, drilling, and bumping, which are common break-in methods. PRO TIP: Get two locks - one for your front door and one for the back door that leads from the garage into your home. Keep the back up keys somewhere safe (maybe one in the garage and one in the house)

3. HOA Rules: What to Check Before Changing Your Locks

Before making any changes, check with your Homeowners Association (HOA) if you live in a community with one. Some HOAs have rules about the type, color, or style of locks that can be used, especially in developments where uniformity is required.

Key HOA Considerations:

• Does the HOA have guidelines on lock color, style, or brand?
  

• Are smart locks or video doorbells allowed? Some communities have privacy restrictions.
  

• If your home has a shared entry system (such as a condo or townhome), does the HOA control the locks?
  

It’s always best to review your community’s guidelines before making changes so you don’t run into compliance issues later.

4. Smart Lock Considerations: Subscription Fees, Weather, and Recording Capabilities

Smart locks offer convenience and security, but before purchasing one, there are a few key factors to consider.

Subscription Fees

Many smart locks with advanced features, such as remote access, activity tracking, and integration with security systems, require a monthly or annual subscription.

Some brands charge extra for features like:

• Cloud storage for access logs and recorded footage

• Temporary guest access codes beyond a basic limit

• Integration with smart home hubs like Alexa, Google Home, or Apple HomeKit

Before purchasing, check if a subscription is required and what features are locked behind a paywall.

Recording Capabilities

Some smart locks come with built-in cameras or work with video doorbells to record entry attempts and log activity. However, not all models store footage locally—you may need a cloud storage plan.

Key things to check:

• Is video recording included or requires a subscription?

• Does the lock store logs locally, or does it need an internet connection?

• Are motion alerts and real-time notifications included?
  

Weather Durability

If you live in extreme climates, such as desert regions with high heat or snowy areas with freezing temperatures, your smart lock needs to withstand harsh weather conditions.

Heat & Sun Exposure – Some smart locks have a maximum operating temperature and can malfunction in extreme heat, especially if your front door gets direct sunlight for long periods. Look for locks rated for high temperatures or those with heat-resistant casings.

Cold & Moisture – In freezing climates, some locks experience battery failures or sluggish keypads. Ensure your lock has weatherproof seals and a battery backup option in case of cold-related failures.

When selecting a smart lock, check the temperature range and IP (Ingress Protection) rating to ensure it’s suitable for your local climate.

5. Added Features for Convenience and Safety

Changing your locks isn’t just about security—it’s also about improving convenience and functionality.

Many modern locks offer features that make life easier, especially for busy homeowners.

Popular Features to Look For:

• Auto-Locking: Set your door to lock automatically after a certain time, preventing accidental unlocks.
  

• Temporary Guest Codes: Perfect for dog walkers, babysitters, or houseguests—grant and revoke access as needed.
  

• Integration with Smart Home Systems: Sync your lock with Amazon Alexa, Google Home, or Apple HomeKit for seamless control.

  
  

• Keyless and Remote Access: Unlock or lock your door from anywhere using your phone.
  

• Tamper Alerts and Activity Logs: Get notified when someone attempts to access your home.

Investing in a lock with these extra features can make home access easier and safer for your family.

6. Do You Need Additional Security Upgrades?

Changing the locks is an excellent first step, but while you're at it, you may want to consider additional security enhancements to fortify your home.

Additional Security Upgrades to Consider:

• Door Reinforcement Plates – Strengthens weak points around locks, making doors harder to kick in.
  

• Security Cameras or Video Doorbells – Record activity around your entry points for extra surveillance.
  

• Window Locks and Sensors – Deter break-ins through first-floor windows.
  

• Garage Door Smart Locks – Prevent unauthorized access to your garage.

If you’ve just moved into a new build, now is the perfect time to assess your home’s overall security and make upgrades before you fully settle in.

Final Thoughts: A Small Change That Makes a Big Difference

Changing the locks on your new build home may not be at the top of your moving to-do list, but it’s a simple, affordable, and effective way to secure your investment.

• Peace of mind – Know that only trusted individuals have access to your home.
  

• Better security – Upgrade from builder-grade locks to high-tech or heavy-duty options.

  
  

• Increased convenience – Take advantage of smart features that improve access and control.
  

• Compliance with HOA rules – Avoid issues by reviewing regulations before making changes.

Your home should feel like your sanctuary, and taking control of your home’s security from day one is an essential step toward protecting your family and property.

So, once you get those moving boxes inside, make changing the locks one of the first things you check off your list!
